Question

7,2 у + 4,5 у = 21,06

Answer 1

Пошаговое объяснение:

7,2у+4,5у=21,06

11,7у=21.06

у=21,06:11,7

у=1,8

Answer 2

To solve the equation 7.2у + 4.5у = 21.06, we can combine the like terms on the left side of the equation:

(7.2 + 4.5)у = 21.06

Adding the coefficients:

11.7у = 21.06

To isolate у, we can divide both sides of the equation by 11.7:

(11.7у)/11.7 = 21.06/11.7

This simplifies to:

у = 1.8

Therefore, the value of у that satisfies the equation is 1.8.
